Use --skip-cluster-management to avoid destroying and recreating the
kind cluster during the stop/start volume retention test. The second
kind create fails on some CI runners due to cgroups detection issues.
Use --delete-volumes to clear PVs so fresh PVCs can bind on restart.
Bind-mount data survives on the host filesystem; provisioner volumes
are recreated fresh.
